Suicidal ideation in early to middle adolescence: sex-specific trajectories and predictors

Bisphenol AF exposure synergistically increases the risk for suicidality among early adolescents with child maltreatment: A prospective cohort study

BACKGROUND

Child maltreatment (CM) is correlated with suicidality risk among adolescents. Additionally, exposure to bisphenol AF (BPAF) may increase this risk. However, the combined effect of CM and BPAF exposure remains unknown and should be further investigated.

METHODS

In this study, 1,475 early adolescents (mean age = 12.48 years) from the Chinese Early Adolescents Cohort were enrolled. Data were collected at three time points with an interval of 12 months between 2019 and 2021. Participants' history of CM and suicidality (including suicidal ideation and suicidal attempts) were evaluated using a self-report questionnaire. Blood samples were obtained from participants to measure serum BPAF concentrations at baseline. Group-based trajectory modeling was employed to identify different developmental trajectories of suicidality across the three waves. After adjusting for potential confounders, the association between CM and BPAF exposure on suicidal ideation and suicidal attempts was assessed using logistic regression and Poisson regression analyses.

RESULTS

Participants with CM were associated with a risk of one- and two-year incident suicidality (all ps < 0.05), and BPAF levels were positively associated with two-year incident suicidal ideation (adjusted OR = 1.68, 95% CI: 1.13-2.50). Additionally, middle and high levels of BPAF exposure synergistically increase the risk for one- and two-year incident suicidal ideation among participants with CM (adjusted ORs = 2.00-3.83). Similarly, participants exposed to high-level BPAF as well as CM were at a greater risk of one- and two-year incident suicidal attempts than those with low-level BPAF exposure and no CM (adjusted incidence rate ratio [IRRs] = 2.82-4.34). Moreover, compared with participants with a low developmental trajectory of suicidality across the three waves, high BPAF exposure exhibited a significant synergistic effect on participants with CM in the persistently high suicidal ideation trajectory and the increasing suicidal attempts trajectory (all ps < 0.05). Sex subgroup analysis revealed that females were more susceptible to the synergistic effect of BPAF and CM exposure on suicidality than males.

CONCLUSIONS

Environmental factors and the psychological status of individuals may synergistically increase their susceptibility to suicidality. These results offer novel insights into enhancing our understanding of suicidality among adolescents.

Longitudinal trajectories of suicidal ideation among child welfare-involved 7- to 12-year-old children

BACKGROUND

Young children involved in the child welfare system (CWS) are at high risk for suicidal ideation (SI) at a time when overall rates of suicide death in this age group are rising. Yet risk factors for and changes in SI over time are poorly understood in this population.

METHOD

We combined data from two large representative longitudinal studies of children involved in the United States CWS. We examined patterns of SI among children who were between ages 7 and 12 years at the initial survey wave (N = 2,186), assessed at three waves using a measure of SI in the past 2 weeks. We conducted a multinomial regression to understand the baseline demographic, child maltreatment, and mental health characteristics that distinguish the trajectories.

RESULTS

There were eight different subgroups (Non-Ideators, Late Ideators, Boomerang Ideators, Delayed Ideators, Desisters, Boomerang Non-Ideators, Late Desisters, and Persisters). Differences in race, type of maltreatment, sex, and mental health symptoms were identified when comparing Persisters (SI at all three waves) to other groups.

CONCLUSIONS

These findings can help researchers and practitioners to develop strategies for better identifying CWS-involved children who are in greatest need of suicide risk monitoring and intervention.

Suicidal Risk Behaviors in Adolescents With Rare Neurodevelopmental Disorders: The Role of Sex, Autistic Traits, and Mental Health Difficulties

OBJECTIVE

Autistic traits are associated with mental health difficulties and risk of suicidal risk behaviors among adolescents. Little is known about how autistic traits affect the mental health of adolescents with rare neurodevelopmental disorders (RNDs). The aim of this study was to investigate the relationship between autistic traits, mental health difficulties, and suicidal risk behaviors in adolescents with RNDs.

METHODS

Parents (N = 93) completed the Child Behavior Checklist, Social Communication Questionnaire, and Social Responsiveness Scale about their adolescent (Mage = 13.1, SD = 2.3, 62.4% females) with an RND (e.g., sex chromosome aneuploidies, Fragile X syndrome, 22q11.2 deletion syndrome). The data were analyzed with hierarchical logistic regression analysis.

RESULTS

The prevalence of suicidal risk behaviors (16.1%) was similar to that reported among autistic youth and was higher among boys than girls. More autistic traits were associated with suicidal risk behaviors in bivariate analysis. In multivariate analysis, more anxiety/depressive symptoms were associated with more suicidal risk behaviors and externalizing problems associated with suicidal risk behaviors beyond autistic traits and anxiety/depressive symptoms.

CONCLUSION

Adolescents with RNDs are at risk of suicidal risk behaviors, especially those with higher levels of autistic traits, anxiety/depressive symptoms, and externalizing problems. Assessment of autistic traits, mental health difficulties, and suicide risk may be indicated for adolescents with RNDs to determine if corresponding intervention is needed.

Suicidal Behaviors in Early Adolescence: The Interaction Between School Connectedness and Mental Health

Previous research has identified mental health symptoms such as depression and aggression as contributing factors associated with suicidal ideation and attempts in adolescence. However, much of this work has focused on older adolescents (ages > 14) resulting in a dearth of knowledge about early adolescents under 12 years. Moreover, much less is known about school connectedness as a protective factor in the relationship between mental health symptoms and suicidal behaviors. This study examined the interaction effect between school connectedness and mental health symptoms on suicidal behaviors among early adolescents aged 9-12 years. Data were drawn from the Fragile Families and Child Wellbeing Study and yielded an analytic sample (n = 2826) that was majority male (52%), Black (53%), and with an average age of 9.3 years. Data were analyzed using multivariate logistic regression. Among participants, 2% experienced suicidal ideation, and 2% experienced suicide attempts. Black adolescents were more than five times more likely to experience a suicide attempt compared to their White peers (AOR = 5.37; 95% CI = 1.71-16.95; p = .004). There was a significant interaction effect between withdrawn depressed symptoms and school connectedness (AOR = .95; 95% CI = .91-98; p = .006), and between aggressive behavior and school connectedness (AOR = 1.02; 95% CI = 1.01-1.03; p = .001) on suicide attempts. School connectedness did not moderate the relationship between mental health symptoms and suicidal ideation. The findings have important practical implications, which are discussed.

Assessing Suicidal Ideation in Young People With Depression: Factor Structure of the Suicidal Ideation Questionnaire

Evaluating suicidal ideation in young people seeking mental health treatment is an important component of clinical assessment and treatment planning. To reduce the burden of youth suicide, we need to improve our understanding of suicidal ideation, its underlying constructs, and how ideation translates into suicidal behaviour. Using exploratory factor analysis, we investigated the dimensionality of the Suicidal Ideation Questionnaire (SIQ) among 273 participants aged 15-25 with Major Depressive Disorder. Area under the receiver operating characteristic curve (AUROC) analysis was used to explore associations between latent factors and actual suicidal behaviour. Findings suggested that the SIQ assesses multiple factors underlying suicidal ideation. AUROC analyses demonstrated that latent factors relating to both active and passive suicidal ideation predicted past-month suicidal behaviour and suicide attempt. These findings contribute to an improved understanding of the complexities of suicidal ideation and relationships with suicidal behaviour in young people with depression.

Correlates and predictors of the severity of suicidal ideation in adolescence: an examination of brain connectomics and psychosocial characteristics

BACKGROUND

Suicidal ideation (SI) typically emerges during adolescence but is challenging to predict. Given the potentially lethal consequences of SI, it is important to identify neurobiological and psychosocial variables explaining the severity of SI in adolescents.

METHODS

In 106 participants (59 female) recruited from the community, we assessed psychosocial characteristics and obtained resting-state fMRI data in early adolescence (baseline: aged 9-13 years). Across 250 brain regions, we assessed local graph theory-based properties of interconnectedness: local efficiency, eigenvector centrality, nodal degree, within-module z-score, and participation coefficient. Four years later (follow-up: ages 13-19 years), participants self-reported their SI severity. We used least absolute shrinkage and selection operator (LASSO) regressions to identify a linear combination of psychosocial and brain-based variables that best explain the severity of SI symptoms at follow-up. Nested-cross-validation yielded model performance statistics for all LASSO models.

RESULTS

A combination of psychosocial and brain-based variables explained subsequent severity of SI (R² = .55); the strongest was internalizing and externalizing symptom severity at follow-up. Follow-up LASSO regressions of psychosocial-only and brain-based-only variables indicated that psychosocial-only variables explained 55% of the variance in SI severity; in contrast, brain-based-only variables performed worse than the null model.

CONCLUSIONS

A linear combination of baseline and follow-up psychosocial variables best explained the severity of SI. Follow-up analyses indicated that graph theory resting-state metrics did not increase the prediction of the severity of SI in adolescents. Attending to internalizing and externalizing symptoms is important in early adolescence; resting-state connectivity properties other than local graph theory metrics might yield a stronger prediction of the severity of SI.

Protective factors for suicidal ideation among Black adolescents indirectly exposed to community violence

OBJECTIVE

Community violence exposure has been identified as a risk factor for Black youth suicide ideation. However, little is known about factors that protect community violence exposed youth against suicide ideation. The current study examined associations between knowledge of family member and peers' community violence exposure and Black youth's subsequent suicidal ideation, and investigated self-worth and social support as protective factors.

METHOD

Participants were a community sample of Black youth (N = 447, 47.4% female; Mage = 11.77, SD = 0.35) who reported about community violence exposure, self-worth, social support, and suicide ideation in grades 6 and 7.

RESULTS

Regression analyses revealed that grade 6 knowledge of family member and peers' community violence exposure was associated with increases in suicide ideation assessed in grade 7. Self-worth attenuated the association between knowledge of others' community violence exposure and suicide ideation for male adolescents. For female adolescents, social support attenuated the association between knowledge of others' community violence and suicide ideation.

CONCLUSIONS

Findings highlight the consequential impact of knowledge about community violence for Black youth's suicidal ideation. Enhancing protective factors for Black youth is an important target for intervening with exposure to violence and reducing suicide ideation.

Relations between parental response to children's negative emotions and suicidal ideation in chinese adolescents: Internalizing problems, emotion regulation, and perceived relationship quality with parents as mediators

Past work points to the crucial role of parents' responses to children's negative emotions (PRCNE) in adolescents' socioemotional adjustment. The presence of suicidal ideation (SI) is an important sign of significant distress and suicide risk. However, research on the relations between PRCNE and adolescents' SI is lacking. This research aimed to investigate whether parental reactions to children's negative emotions (PRCNE) was related to adolescents' SI and, if so, through which processes. This research utilized data from a sample of Chinese adolescent families (N = 4,574; Parents: 35.81% males, M = 44.07 years old; Adolescents: 55.40% males, M = 16.28 years old), with parents giving their reports on PRCNE and adolescents self-evaluating their psychosocial development (i.e., internalizing problems, emotion regulation, perceived relationship quality with parents) and SI. We examined the relations between six types of PRCNE and adolescents' SI, and analyzed the mediating roles of adolescents' internalizing problems, emotion regulation (i.e., cognitive reappraisal and expressive suppression), and perceived relationship quality with parents. The results showed that emotion-focused response, problem-focused response, and expression encouragement negatively predicted, while punitive response and distress response positively predicted adolescents' SI. However, no statistically significant association emerged between minimization and adolescents' SI. Moreover, adolescents' internalizing problems, usage of expressive suppression, and perceived relationship quality with parents could mediate the relations between PRCNE and adolescents' SI. Contrary to our hypothesis, the results did not support an indirect effect of PRCNE on adolescents' SI through adolescents' cognitive reappraisal. The present research illuminates adolescents' SI by emphasizing the roles of PRCNE. The findings also highlight the importance of paying attention to adolescents' internalizing problems, expressive suppression, and perceived relationship quality with parents in relation to PRCNE in interventions aimed at reducing adolescents' SI.

Use of electronic vaping products and mental health among adolescent high school students in the United States: The moderating effect of sex

Although studies have investigated the association between conventional tobacco smoking and mental health outcomes among adolescents in the United States, few studies have examined the association between electronic vaping products (EVPs) and mental health among adolescents. This study aimed to investigate the cross-sectional association between EVPs use, symptoms of depression, and suicidal behaviors among adolescents. Data were pooled from the 2017 and 2019 Youth Risk Behavior Survey. An analytic sample of 14,285 adolescents (50.3% female) was analyzed using binary logistic regression. The outcome variables investigated were symptoms of depression, suicidal ideation, suicide plan, and suicide attempts, and the main explanatory variable was EVPs use. Of the 14,285 adolescents, 22.2%, 19.2%, and 58.8% were current, former and never users of EVPs, respectively. Controlling for other factors, current users of EVPs were significantly more likely to report having symptoms of depression (AOR = 1.82, 95% CI = 1.58-2.09), having suicidal ideation (AOR = 1.55, 95% CI = 1.30-1.86), making a suicide plan (AOR = 1.62, 95% CI = 1.34-1.97), or attempting suicide (AOR = 1.75, 95% CI = 1.41-2.18) when compared to never users of EVPs. Gender moderated the association between EVPs use, symptoms of depression, suicidal ideation, and suicide plan. Racial minority identity, sexual minority identity, sexual violence victimization, victim of school and cyberbullying, alcohol use, and cigarette smoking were all significantly associated with depression and suicidal behaviors. Study findings support the association between EVPs use and adolescent mental health. Future studies that employ longitudinal designs may offer more insight into the mechanisms underlying this association.

The relationship between daily positive future thinking and past-week suicidal ideation in youth: An experience sampling study

Reduced positive future thinking has been associated with suicidal ideation and behavior in adults, and appears to be exacerbated by negative affect. Yet, this has received little attention in youth. Prior research has also focused on longer-term future thinking, e.g., months and years, and relied on lab-based assessments. Using the experience sampling method (ESM), we investigated whether short-term future thinking in daily life was associated with suicidal ideation in youth and explored the role of affect in the future thinking-suicidal ideation relationship. A community sample of N = 722 adolescent twins and their non-twin siblings completed ESM as part of the TwinssCan study (n = 55 with, and n = 667 without, past-week suicidal ideation). Participants completed self-report questionnaires, including on past-week suicidal ideation as part of the SCL-90. Subsequently, daily future thinking was assessed each morning for six days with ESM. To investigate the relationship between daily positive future thinking and past-week suicidal ideation, we estimated a mixed-effects linear regression model with a random intercept for participant, including age and sex as covariates. The relationship between daily positive future thinking, past-week suicidal ideation, and average positive and negative affect from the previous day was investigated by estimating two separate mixed-effects linear regression models (one for negative affect, one for positive affect), with a random intercept for participant, and random slopes for average positive and negative affect. Our results showed that participants reporting higher past-week suicidal ideation also reported significantly less daily positive future thinking during the ESM period, and this association remained significant when controlling for previous-day average positive and negative affect. Higher average positive affect from the previous day was significantly associated with higher positive future thinking. Although average negative affect from the previous day was associated with lower positive future thinking, this association was not statistically significant. Our findings indicate that short-term future thinking relates to suicidal ideation among a non-clinical sample of adolescents. Future research should investigate the directionality of the future thinking-suicidal ideation relationship, in order to investigate whether impaired future thinking may be an early warning signal for escalating suicidal ideation in youth.

Longitudinal predictors of suicidal ideation: Emerging to early adulthood

Few studies have examined the longitudinal trajectory of suicidal ideation (SI) in community samples, particularly during emerging adulthood. Additionally, there is scant data on predictors of longer-term course of SI across this period. We examined multiple domains of adolescent psychosocial and clinical functioning as predictors of SI trajectory and explored whether biological sex moderates those associations. The data came from the Oregon Adolescent Depression Project. Participants completed self-reports of psychosocial and clinical functioning and interviews assessing psychopathology in mid-late adolescence. SI was assessed using up to seven annual mailer assessments spanning ages 19-31. Multilevel growth models found that SI declined across emerging adulthood. Multiple indices of adolescent functioning were associated with higher levels of SI three years later. Few adolescent functioning constructs predicted faster reductions in SI, and no constructs predicted slower longitudinal reductions (or increases) in SI. Similar associations were found when controlling for adolescent SI. Lastly, we found little evidence for sex differences in these associations. This work shows that adolescent functioning is largely associated with initial and enduring levels of SI. Moreover, associations were similar between sexes. Given the modest associations found across long periods of time, future research should focus on proximal risk factors for SI.

Perceived Social Status and Suicidal Ideation in Maltreated Children and Adolescents

Recent decades have seen an alarming increase in rates of suicide among young people, including children and adolescents (“youth”). Although child maltreatment constitutes a well-established risk factor for suicidal ideation in youth, few efforts have focused on identifying factors associated with maltreated youths’ increased risk for suicidal ideation, especially across development. The present study examined the relations between maltreated youths' (N = 279, M = 12.06 years, 52% female, 53% Latinx) perceptions of their social status and suicidal ideation and compared those relations between pre-adolescents and adolescents. Findings revealed unique developmental patterns: Perceived social status was associated with suicidal ideation, but only in adolescents, who showed greater risk for suicidal ideation if they viewed themselves as lower ranked in society and lower risk for suicidal ideation if they viewed themselves as higher ranked in society. Findings have implications for scientific and practical efforts aimed at better understanding and preventing suicide in a high-risk developmental population.

Substance use disorders and suicidality in youth: A systematic review and meta-analysis with a focus on the direction of the association

BACKGROUND

Reviews and meta-analyses suggest that substance use and suicidality (i.e., suicidal ideations and attempts) are associated in youth, but the direction of this association remains unclear. Theoretically, the secondary psychiatric disorder hypothesis (SPDH) posits that substance use leads to suicidality, while the secondary substance use disorder hypothesis (SSUDH) posits that suicidality leads to substance use. To clarify these associations, this meta-analysis systematically reviewed studies that examined the prospective associations between SUDs and suicidality in youth (age 25 and younger) and compared results according to the direction of the association.

METHODS

Web of Science, Embase, PsycINFO, PubMed, Medline and ProQuest Dissertations & Theses Global were searched from inception to March 8, 2020, and 55 effect sizes from 23 samples were included and analyzed using a three-level meta-analysis.

RESULTS

SUDs significantly predicted subsequent suicidality (OR = 2.16, 95%CI 1.57-2.97), suicidality significantly predicted subsequent SUDs (OR = 2.16, 95%CI 1.53-3.04), and these effect sizes did not differ (p = 0.49).

CONCLUSIONS

Considering that 65% of reviewed studies only examined the SPDH, this review highlights that more attention should be given to the SSUDH, and that studies should examine bidirectional associations between SUDs and suicidality across time. Clinically, because SUDs and suicidality were found to influence each other, results suggest that mental health and SUDs should ideally be detected and treated early, and that co-occurring disorders should be assessed and treated concomitantly.

Suicidality in 12-Year-Olds: The Interaction Between Social Connectedness and Mental Health

Suicidal thoughts and behaviors (STB) are a leading cause of death in adolescence. To date, most research with youth has focused on risk factors for suicide; and less attention has been paid to resilience factors. This study examined whether positive beliefs and social connectedness moderate associations between mental health symptoms and STB. A community sample of 12-year-olds (N = 60) completed self-report questionnaires on their STB, mental health symptoms, positive beliefs and social connectedness. Nearly 20% of the adolescents reported STB. STB was associated with increased mental health symptoms and lower scores on the resilience measures. A significant moderating effect of social connectedness showed that youth with a combination of poor mental health and high levels of social support exhibited lower levels of STB. There was no significant moderating effect of positive beliefs. These results indicate that social support should be screened for in primary care and incorporated into youth suicide prevention programs.

Trajectories of suicide attempts from early adolescence to emerging adulthood: prospective 11-year follow-up of a Canadian cohort

BACKGROUND

Suicide is a leading cause of mortality in youth, yet the course of suicide attempts is poorly documented. We explored the vulnerable transition from adolescence to emerging adulthood to identify group trajectories and risk factors.

METHODS

The National Longitudinal Survey of Children and Youth is a prospective representative cohort of Canadian children. We followed participants aged 7-11 years in 1994-95 to age 23 (2008-09). We modelled self-reported past-year suicide attempts (ages 12 to 23 years) using growth mixture models. We analysed risk factors from self- and parent-report questionnaires at pre-adolescence (ages 10-11) and early adolescence (ages 12-13) using multinomial logistic regressions. Analyses were adjusted for sample non-response and attrition.

RESULTS

In 2233 participants answering questions on teen and adult suicide attempts, we identified three trajectories: never attempted (96.0%), adolescence-limited (2.0%) and persisting into adulthood (2.0%). Adolescent girls aged 12-13 with depression/anxiety symptoms, and with mothers experiencing depression had higher risks of adolescence-limited than never-attempted [relative risk RR 9.27 (95% confidence interval: 1.73-49.82); 2.03 (1.02-3.32), for each standard deviation increase; 1.07 (1.00-1.15); respectively]. Preteen ADHD symptoms increased the risk of attempts persisting into adulthood as compared to never-attempted [RR 2.05 (1.29-3.28) for each standard deviation increase]. Suicide death of schoolmate/acquaintance increased risks of an adulthood trajectory as compared to never-attempted and adolescence-limited [RR 8.41 (3.04-23.27) and 6.63 (1.29-34.06), respectively].

CONCLUSION

In half the participants attempting suicide, attempts continued into adulthood. We stress the need for preventive strategies in early adolescence and differential clinical/educational interventions as identified for each trajectory.

Association of Childhood Adversities With Suicide Ideation and Attempts in Puerto Rican Young Adults

Importance

Racial/ethnic and sex disparities in suicide ideation and attempts are well established, with higher risk of suicide ideation and attempt among US racial/ethnic minority school-aged youths (than their White peers) and girls and women (than boys and men). The suicide-related risk of racial/ethnic minority young adults, especially young women, may be strongly influenced by adverse childhood experiences, known early determinants of suicide ideation and attempts.

Objectives

To assess lifetime and past-year prevalence estimates of suicide ideation and suicide attempt and to examine sex differences in the role of adverse childhood experiences as a prospective risk factor for Puerto Rican young adults from 2 sociocultural contexts.

Design, Setting, and Participants

Data in this longitudinal cohort study are from 4 waves of the Boricua Youth Study, a population-based cohort study of Puerto Rican children from San Juan and Caguas, Puerto Rico, and the South Bronx, New York, 5 to 17 years of age (N = 2491; waves 1-3: 2000-2004) and 15 to 29 years of age (wave 4: 2013-2017). Data analysis was performed from February 26, 2019, to October 16, 2020.

Exposures

Adverse childhood experiences were assessed by interview in childhood and early adolescence (waves 1-3) and included child maltreatment (physical, sexual, and emotional abuse and neglect), exposure to violence, parental loss (separation, divorce, and death), and parental maladjustment (mental health problems, substance or alcohol abuse, intimate partner violence, and incarceration).

Main Outcomes and Measures

Lifetime and past-year suicide ideation and attempt were assessed in young adulthood (wave 4) using the World Health Organization Composite International Diagnostic Interview.

Results

Among 2004 Puerto Rican young adults (80.4% of the original cohort; mean [SD] age, 22.9 [2.8] years; 1019 [50.8%] male), young women compared with young men had a higher prevalence of lifetime suicide attempt (9.5% vs 3.6%) and lifetime suicide ideation (16.4% vs 11.5%), whereas past-year suicide ideation (4.4% vs 2.4%) was not statistically different. Logistic regression models, adjusting for demographics and lifetime psychiatric disorders, found that young women but not young men with more adverse childhood experiences had higher odds of suicide ideation (lifetime; odds ratio [OR], 2.44; 95% CI, 1.54-3.87; past year: OR, 2.56; 95% CI, 1.18-5.55). More adverse childhood experiences were also prospectively associated with lifetime suicide attempt (OR, 1.16; 95% CI, 1.04-1.29), irrespective of sex.

Conclusions and Relevance

The findings of this cohort study suggest that, among Puerto Rican young adults from 2 different sociocultural contexts, adverse childhood experiences were relevant to understanding suicide attempt and suicide ideation, the latter specifically among young women. The prevention of cumulative adverse childhood experiences could reduce later risk of suicide attempts and, among young women, for suicide ideation.

Displayed Depression Symptoms on Facebook at Two Time Points: Content Analysis

Background

Depression is a prevalent and problematic mental disorder that often has an onset in adolescence. Previous studies have illustrated that depression disclosures on social media are common and may be linked to an individual’s experiences of depression. However, most studies have examined depression displays on social media at a single time point.

Objective

This study aims to investigate displayed depression symptoms on Facebook at 2 developmental time points based on symptom type and gender.

Methods

Participants were recruited from an ongoing longitudinal cohort study. The content analysis of text-based Facebook data over 1 year was conducted at 2 time points: time 1 (adolescence; age 17-18 years) and time 2 (young adulthood; ages 20-22 years). Diagnostic criteria for depression were applied to each post to identify the displayed depression symptoms. Data were extracted verbatim. The analysis included nonparametric tests for comparisons.

Results

A total of 78 participants’ Facebook profiles were examined, of which 40 (51%) were male. At time 1, 62% (48/78) of the adolescents had a Facebook profile, and 54% (26/78) displayed depression symptom references with an average of 9.4 (SD 3.1) references and 3.3 (SD 2.3) symptom types. Of the 78 participants, 15 (19%) females and 12 (15%) males displayed depression symptom references; these prevalence estimates were not significantly different by gender (P=.59). At time 2, 35 young adults displayed symptoms of depression with an average of 4.6 (SD 2.3) references and 2.4 (SD 1.3) symptom types. There were no differences in the prevalence of symptoms of depression displayed between males (n=19) and females (n=16; P=.63).

Conclusions

This content analysis study within an ongoing cohort study illustrates the differences in depression displays on Facebook by developmental stage and symptom. This study contributes to a growing body of literature by showing that using social media to observe and understand depression during the emerging adult developmental period may be a valuable approach.

Associations between insecure attachment styles to parents and suicidal ideation in adolescents with depression

Objective

Suicidal ideation and depressive symptoms are often interrelated in clinical settings. Insecure attachment may be a risk factor for suicidal ideation in depressed adolescents. To our knowledge, this study is the first to examine the association between self-reported insecure attachment styles to both parents and suicidal ideation in a clinical sample of adolescents with depression.

Methods

Fifty clinically depressed adolescents (13-17 years, 84% girls) completed self-reported measures of suicidal ideation, depressive symptoms, and attachment style to parents.

Results

There was a statistically significant bivariate association between higher levels of attachment anxiety in relation to mothers and fathers and higher levels of suicidal ideation. When attachments to both parents were included in the same multivariate model, only attachment anxiety to the mother was significantly associated with the level of suicidal ideation. Self-reported depressive symptoms remained significantly associated with the level of suicidal ideation in all analyses. Younger adolescents with attachment anxiety reported higher levels of suicidal ideation than older adolescents.

Conclusion

Conclusions about directionality and causality of associations between insecure attachment and suicidal ideation are limited due to the cross-sectional design. Our findings suggest that attachment anxiety in relation to the mother and father is associated with increased levels of suicidal ideation. Implication of these findings for treatment selection is discussed.

Childhood maltreatment, psychiatric symptoms, and suicidal thoughts among adolescents receiving substance use treatment services

INTRODUCTION

Childhood maltreatment experiences are associated with future suicidal thoughts and suicide attempts, yet the roles of specific psychiatric symptoms mediating this relation remain to be clarified. To clarify these relations, we tested a model incorporating multiple forms of childhood maltreatment (sexual abuse, physical punishment, emotional neglect), past year psychiatric disorder symptoms during adolescence (anxiety, mood, and conduct disorders) and recent suicidal thoughts.

METHODS

We administered structured interviews to 394 adolescents receiving outpatient substance use treatment services in the Southeastern United States (280 males; Mage = 16.33; SDage = 1.15). Structural equation models (SEMs) were used to evaluate the degree to which relations between childhood maltreatment and suicidal thoughts were mediated by specific past-year psychiatric symptoms.

RESULTS

Mood disorder symptoms significantly mediated the relation between neglect/negative home environment and suicidal thoughts. This path of influence did not vary by gender.

CONCLUSIONS

Childhood maltreatment and subsequent psychopathology influence suicidal thoughts among adolescents receiving substance use treatment services. The findings of the present study have implications for the adaptation and delivery of substance use treatment services to adolescents to enhance treatment engagement and outcomes.

Associations Between Weight Perception, Unhealthy Weight Control Behavior, and Suicidal Ideation and Planning Among Korean Adolescents: A National Cross-Sectional Secondary Analysis

PURPOSE

This study aimed to investigate the associations between weight perception, unhealthy weight control behavior, and suicidal ideation and planning and identify the role of unhealthy weight control behavior as a mediator in these associations among Korean adolescents.

DESIGN AND METHODS

This national cross-sectional secondary study used data from the 2015-2017 Korea Youth Risk Behavior Web-Based Surveys, with a final sample of 96,285 adolescents who tried to manage their weight in the 30 days prior to the surveys. A multivariate logistic regression was conducted.

RESULTS

Both adolescent groups who perceived themselves to be underweight or overweight were significantly linked to a greater likelihood of suicidal ideation and planning (COR, 95% CI = 1.249, 1.141-1.367; COR, 95% CI = 1.339, 1.282-1.399) respectively. While adolescents with perceptions of being underweight are associated with suicidal ideation and planning through the suppression effect of unhealthy weight control behavior (Pathway A: OR, 95% CI = 0.628, 0.587-0.671), adolescents with perceptions of being overweight are linked with the same through the mediation effect (Pathway A: OR, 95% CI = 1.195, 1.141-1.251).

CONCLUSIONS

Adolescents with perceptions of being overweight are highly likely to have unhealthy weight control behavior that can be linked to the possibility of suicidal ideation and planning, while adolescents with perceptions of being underweight are comparatively less likely to engage in such behavior.

PRACTICE IMPLICATIONS

It is necessary to identify the status of weight perception among adolescents and closely monitor the unhealthy weight control behavior to prevent suicidal ideation and planning.

Secular trends in suicidal ideation and associated factors among adolescents

Objectives:

Suicide is one of the leading causes of death in adolescence, and the second most common cause of death among young people. The objective of this study was to identify trends in suicidal ideation by sex and ascertain factors associated with this outcome.

Methods:

Secular trend study with statewide coverage conducted at 5-year intervals, with 4,207 adolescents (2006), 6,264 adolescents (2011) and 6,026 adolescents (2016). Logistic regression was used to evaluate the secular trend of suicidal ideation. Multilevel logistic regressions evaluated the factors associated with suicidal ideation in the survey conducted in 2016.

Results:

There was a positive trend in suicidal ideation prevalence in 2016 compared to the prevalence in 2006 and 2011, in both boys and girls. Low social support, poor sleep quality, and low parental supervision were associated with suicidal ideation in boys and girls. Exposure to violence and bullying was associated with suicidal ideation only in girls. TV time and computer and videogame time were not associated with suicidal ideation in boys or girls.

Conclusion:

There is an alarming trend of increased suicidal ideation in adolescents. Several dimensions were associated with suicidal ideation in adolescents, especially social support, sleep quality, and parental supervision.

Suicide Attempts and Course of Suicidal Ideation among Puerto Rican Early Adolescents

Suicidal behavior increases substantially during early adolescence, a critical understudied developmental period. This study reports on the prevalence of suicidal ideation, suicide attempts, and course of suicidal ideation among Puerto Rican early adolescents, a high-risk group for suicidal behavior in adulthood. Gender differences and the prospective association of psychiatric disorders with course of suicidal ideation are examined. Participants were 1228 Puerto Rican adolescents (ages 10-13 at wave 1; 48% female) and parents, selected through probability-based sampling, assessed yearly across three waves. Adolescents and parents reported via Diagnostic Interview Schedule for Children-IV about 12-month suicide attempts and suicidal ideation (further categorized as never present, onset, recurrence, and remission), mood and anxiety disorders; parents reported on disruptive disorders. Over the three waves, 9.5% early adolescents thought about suicide and 2.1% attempted suicide. In adjusted multinomial regression models, compared to those with never present suicidal ideation, female gender was related to onset of suicidal ideation (OR = 2.60; 95% CI, 1.22-5.55). Disruptive disorders were related to onset (OR = 5.80; 95% CI, 2.06-16.32) and recurrence of suicidal ideation (OR = 5.07, 95% CI, 1.14-22.47), mood disorders were related to remission (OR = 14.42, 95% CI, 3.90-53.23), and anxiety disorders to onset of suicidal ideation (OR = 3.68, 95% CI, 1.75-7.73). Our findings inform strategies tailored for early adolescents. To address onset of suicidal ideation, prevention should focus on girls and those with anxiety or disruptive disorders. When ideation is recurrent, interventions oriented to reduce disruptive behavior and its consequences may help achieve remission.

Assessing mental health in vulnerable adolescents

Depressive symptom severity mediates the association between avoidant problem-solving style and suicidal ideation

BACKGROUND

The contemporaneous association between avoidant style, a maladaptive social problem-solving strategy, and adolescent suicidal ideation has been well established. However, the mechanisms underlying this association are not well understood. Using cross-lagged panel modeling, the present study examined whether depressive symptom severity mediates the relation between avoidant style and severity of suicidal ideation. The specificity of depressive symptom severity as a mediator was also evaluated by simultaneously testing whether avoidant style mediates the association between depressive symptom and suicidal ideation severity.

METHODS

The sample included 110 adolescents enrolled in a randomized controlled clinical effectiveness trial. Avoidant style as well as depressive symptom and suicidal ideation severity were assessed via self-report with the Social Problem-Solving Inventory-Revised, Children's Depression Scale-2, and Suicidal Ideation Questionnaire-Junior, respectively, at baseline, 3-and 6-months.

RESULTS

After accounting for participant age, sex, and treatment condition, path analyses supported the specificity of 3-month depressive symptom severity as a mediator of the association between baseline levels of avoidant style and 6-month suicidal ideation severity.

LIMITATIONS

Results may not be generalizable to non-clinical samples. Causality cannot be inferred from study results. Data were exclusively collected via self-report.

CONCLUSIONS

Findings suggest that avoidant style is indirectly related to suicidal ideation through depressive symptom severity. Thus, treatment targeted at improving social problem-solving skills, particularly avoidant style, may help reduce depressive symptoms and lower suicide risk.

Implementation Determinants and Outcomes of a Technology-Enabled Service Targeting Suicide Risk in High Schools: Mixed Methods Study

BACKGROUND

Technology-enabled services (TESs), which integrate human service and digital components, are popular strategies to increase the reach and impact of mental health interventions, but large-scale implementation of TESs has lagged behind their potential.

OBJECTIVE

This study applied a mixed qualitative and quantitative approach to gather input from multiple key user groups (students and educators) and to understand the factors that support successful implementation (implementation determinants) and implementation outcomes of a TES for universal screening, ongoing monitoring, and support for suicide risk management in the school setting.

METHODS

A total of 111 students in the 9th to 12th grade completed measures regarding implementation outcomes (acceptability, feasibility, and appropriateness) via an open-ended survey. A total of 9 school personnel (school-based mental health clinicians, nurses, and administrators) completed laboratory-based usability testing of a dashboard tracking the suicide risk of students, quantitative measures, and qualitative interviews to understand key implementation outcomes and determinants. School personnel were presented with a series of scenarios and common tasks focused on the basic features and functions of the dashboard. Directed content analysis based on the Consolidated Framework for Implementation Research was used to extract multilevel determinants (ie, the barriers or facilitators at the levels of the outer setting, inner setting, individuals, intervention, and implementation process) related to positive implementation outcomes of the TES.

RESULTS

Overarching themes related to implementation determinants and outcomes suggest that both student and school personnel users view TESs for suicide prevention as moderately feasible and acceptable based on the Acceptability of Intervention Measure and Feasibility of Intervention Measure and as needing improvements in usability based on the System Usability Scale. Qualitative results suggest that students and school personnel view passive data collection based on social media data as a relative advantage to the current system; however, the findings indicate that the TES and the school setting need to address issues of privacy, integration into existing workflows and communication patterns, and options for individualization for student-centered care.

CONCLUSIONS

Innovative suicide prevention strategies that rely on passive data collection in the school context are a promising and appealing idea. Usability testing identified key issues for revision to facilitate widespread implementation.

Suicidal Behavior in Adolescents: A Latent Class Analysis

The main goal of the present study was to identify and validate latent classes of suicidal behavior in a representative sample of adolescents. The sample comprised a total of 1506 students, including 667 males (44.3%), selected through a sample stratified by clusters. The mean age was 16.15 years (SD = 1.36). The instruments used evaluated suicidal behavior, positive and negative affect, emotional and behavioral problems, prosocial behavior, and subjective well-being. Using the Paykel Suicide Scale, the latent class analysis identified four homogeneous subgroups: “low risk”, “suicidal act”, “suicidal ideation”, and “high risk for suicide”. These subgroups presented a differential pattern in terms of their social-emotional adjustment. The subgroups with the highest theoretical risk showed lower scores on subjective well-being and positive affect as well as higher scores on emotional and behavioral problems and negative affect compared to the non-risk subgroups. This study contributes to an understanding of the typologies of suicidal behavior among adolescents and the relationship with psychopathological adjustment. Ultimately, these findings may promote the development or improvement of early detection and prevention strategies in the suicidal behavior field in order to reduce the socio-economic burdens associated with suicide in young populations.

Prospective Investigation of the Interaction Between Social Problems and Neuropsychological Characteristics on the Development of Suicide Ideation

OBJECTIVE

Negative social interactions are known to contribute to the development of suicide ideation. However, it is unclear how this risk factor interacts with other predisposing risk factors. The purpose of this study was to determine how social and neuropsychological factors interact as a prospective predictor of the emergence of suicide ideation in adolescents.

METHOD

Data were collected from adolescents (M age = 13.12, SD = 1.48) over 3 years as part of a larger study. Participants completed the MINI-Kid and Youth Self-Report, which were used to assess for suicidality. Negative social interactions were operationalized as the Social Problems scale of the YSR. Additionally, adolescents completed a neuropsychological battery at each wave of data collection.

RESULTS

Logistic moderation analyses demonstrated a significant interaction between task switching and endorsement of negative social interactions in the prediction of suicide ideation one year later, Wald χ² (1) = 4.94, OR = 0.90, p < .05. Distractibility was a significant predictor, Wald χ² (1) = 5.52, OR = 3.45, p < .05, but it did not demonstrate an interaction effect. Perseveration failed to reach statistical significance independently and in the interaction.

CONCLUSIONS

The results indicate that certain neuropsychological characteristics can aid in predicting which adolescents will develop suicide ideation in the presence of negative social interactions, which may have significant clinical implications.

Association Between Bullying and Suicidal Behavior Among Chinese Adolescents: An Analysis of Gender Differences

Background

Suicide has become the leading cause of death among 15-34 years old in China, and more attention should be paid to risk factors and prevention of suicidal ideation and suicide attempts. The school-based survey was conducted to test the associations of bullying behavior with suicidal ideation and suicide attempts, and to assess whether the biological gender can moderate these associations.

Methods

A multistage stratified cluster sampling method was used to recruit participants from high schools in Guizhou, China, and univariate and multivariate logistic regression models were fitted.

Results

A total of 23,392 students were included in the analysis, and 45.4% were boys. The mean age of the students was 15.2 (SD: 1.9) years. Overall, 3.8% (882) of the students were victims, 4.9% (1144) were bullies, and 3.2% (736) were bully-victims. A total of 18.9% of students reported having suicidal ideation, and 3.9% reported having suicide attempts. Victims (adjusted odds ratio [AOR]=2.15, 95% CI=1.84-2.51), bullies (AOR=3.17, 95% CI=2.78-3.62), and bully-victims (AOR=3.18, 95% CI=2.71-3.73) were at an elevated risk of suicidal ideation than neutrals; similar associations can be found in the associations between bullying behavior and suicide attempts. Further stratification analyses showed that the associations of being bullied or bullying others with suicidal ideation and suicide attempts were slightly stronger in girls than in boys.

Conclusion

Prevention or intervention programs are recommended to take the biological gender into consideration, and future studies are also warranted to investigate the reasons of differences by gender in the association of bullying and suicidal behavior.

Management of Suicidal Adolescents Presenting to the Emergency Department

Background:

Increasingly, adolescents are presented to hospital emergency departments with suicidal ideation (SI) and depression. Even among those who come in with other complaints, depression and SI are common. Emergency personnel are placed in the default position of providing care for these patients, but often lack sufficient knowledge and skills to do this effectively.

Objective:

The aim of this paper is to offer guidance to emergency personnel and describe goals and strategies for screening and brief interventions.

Method:

We review risk factors, assessment tools and evidence-based interventions that can be utilized by mental health professionals working in EDs and by ED staff in the absence of mental health professionals.

Conclusion:

Emergency departments can serve a critical role in risk management and treatment of adolescent depression and suicidal ideation. All patients presenting to the ED should be screened for current and past depression and suicidal ideation or attempts. Brief interventions can be delivered in the ED that can increase the likelihood that patients will receive follow- up care.

Prevalence, Onset, and Course of Suicidal Behavior Among Adolescents and Young Adults in Germany

Importance

Suicidal behavior is a leading cause of death among adolescents and young adults. In light of the ideation-to-action framework, the delineation of frequency and temporal characteristics of such behavior during this developmental period is crucial.

Objectives

To provide lifetime and 12-month prevalence estimates of suicidal behavior, including ideation, plan, and attempt, in adolescents and young adults of the general population, and to provide information about age at onset, temporal characteristics of suicidal behavior, including duration (number of years between onset and last occurrence) and frequency (number of episodes), and transition patterns across suicidal behaviors.

Design, Setting, and Participants

A cross-sectional epidemiological study was conducted in a random community sample of 1180 adolescents and young adults aged 14 to 21 years assessed in 2015 to 2016 in Dresden, Germany. Data analysis was performed from October 2018 to March 2019.

Main Outcomes and Measures

Lifetime and 12-month suicidal behavior (ideation, plan, and attempt) were assessed with a standardized diagnostic interview (Munich-Composite International Diagnostic Interview) by trained clinical interviewers. The onset, frequency, and duration of suicidal behavior were assessed by questionnaire.

Results

Of the 1180 participants (495 male [weighted percentage, 51.7%]; mean [SD] age, 17.9 [2.3] years), 130 participants (10.7%; 95% CI, 9.0%-12.8%), 65 participants (5.0%; 95% CI, 3.9%-6.5%), and 41 participants (3.4%; 95% CI, 2.4%-4.7%) reported lifetime suicidal ideation, plan, and attempt, respectively. Any lifetime suicidal behavior was reported by 138 participants (11.5%; 95% CI, 9.7%-13.7%). Age-specific cumulative incidence estimates indicated an increase in suicidal behavior during adolescence, starting at age 10 years (<1%), increasing slightly until the age of 12 years (2.2%), and then increasing sharply thereafter until age 20 years (13.5%). There were different patterns among female and male participants for ideation, plan, and attempt, with an overall higher incidence among female participants for ideation (hazard ratio, 1.51; 95% CI, 1.02-2.22; P = .04), for plan (hazard ratio, 3.31; 95% CI, 1.72-6.36; P < .001), and, among those older than 14 years, for attempt (hazard ratio, 3.07; 95% CI, 1.11-8.49; P = .03). Of those with suicidal ideation, 66.0% reported persistent or recurrent ideation over more than 1 year with 75.0% reporting more than 1 episode. Of the participants with lifetime suicidal ideation, 47.0% reported a suicide plan and 23.9% reported a suicide attempt. The transition to suicide plan or attempt occurred mainly in the year of onset of suicidal ideation or plan; of those who transitioned, 74.9% transitioned from ideation to plan, 71.2% transitioned from ideation to attempt, and 85.4% transitioned from plan to attempt in the same year.

Conclusions and Relevance

There is an urgent public health need for timely identification of suicidal behavior in adolescents and young adults to terminate persistent or recurrent suicidal tendencies and to interrupt the ideation-to-action transition.

Psychopathological mechanisms of early neglect and abuse on suicidal ideation and self-harm in middle childhood

Informed by diathesis-stress models of suicide risk, this longitudinal study examines the psychopathological mechanisms through which early maltreatment increases the risk for suicidal ideation and self-harm in middle childhood. The sample included 2958 families from the Fragile Families and Child Wellbeing Study, who participated in interviews at child's ages of 3 and/or 5, and 9. Via the Child Behavior Checklist, primary caregivers reported on the child's suicidal ideation and self-harm at age 9 and on clinically elevated depressive/anxious symptoms, aggressive behaviors, attention problems, and comorbid aggression and depressive/anxious symptoms at age 5. Past year neglect and physical/psychological abuse were measured via the Parent-Child Conflict Tactics Scale at age 3. Multivariate structural equation models indicated that early neglect had a significant indirect effect on suicidal ideation via clinically elevated depressive/anxious symptoms (OR = 1.57, 95% CI 1.09-2.25) and comorbid symptomatology (OR = 1.28, 95% CI 1.02-1.62), and on self-harm also via clinically elevated depressive/anxious symptoms (OR = 1.39, 95% CI 1.04-1.84) and comorbid symptomatology (OR = 1.20, 95% CI 1.01-1.43). Early physical/psychological abuse had a significant indirect effect on self-harm via clinically elevated attention problems (OR = 1.09, 95% CI 1.01-1.21). Unique developmental pathways for suicidal ideation and self-harm emerged among children exposed to abuse or neglect. For those exposed to early neglect, interventions should target depressive/anxious symptoms, especially when comorbid with aggression, to prevent suicidal ideation and self-harm. For children exposed to early physical/psychological abuse, problems with attention and impulsivity may be targets for reducing the risk for self-harm.

Neurocognitive functioning in community youth with suicidal ideation: gender and pubertal effects

BACKGROUND

Although there are extensive data on clinical psychopathology in youth with suicidal ideation, data are lacking regarding their neurocognitive function.

AIMS

To characterise the cognitive profile of youth with suicidal ideation in a community sample and evaluate gender differences and pubertal status effects.

METHOD

Participants (N = 6151, age 11-21 years, 54.9% females) from the Philadelphia Neurodevelopmental Cohort, a non-help-seeking community sample, underwent detailed clinical evaluation. Cognitive phenotyping included executive functioning, episodic memory, complex reasoning and social cognitive functioning. We compared participants with suicidal ideation (N = 672) and without suicidal ideation (N = 5479). Regression models were employed to evaluate differences in cognitive performance and functional level, with gender and pubertal status as independent variables. Models controlled for lifetime depression or general psychopathology, and for covariates including age and socioeconomic status.

RESULTS

Youth with suicidal ideation showed greater psychopathology, poorer level of function but better overall neurocognitive performance. Greater functional impairment was observed in females with suicidal ideation (suicidal ideation × gender interaction, t = 3.091, P = 0.002). Greater neurocognition was associated with suicidal ideation post-puberty (suicidal ideation × puberty interaction, t = 3.057, P = 0.002). Exploratory analyses of specific neurocognitive domains showed that suicidal ideation-associated cognitive superiority was more prominent in post-pubertal males compared with females (Cohen's d = 0.32 and d = 0.11, respectively) across all cognitive domains.

CONCLUSIONS

Suicidal ideation was associated with poorer functioning yet better cognitive performance, especially in post-pubertal males, as measured by a comprehensive cognitive battery. Findings point to gender and pubertal-status specificity in the relationship between suicidal ideation, cognition and function in youth.

Trajectories of Suicidal Ideation from Middle Childhood to Early Adolescence: Risk and Protective Factors

Suicidal ideation is considered to be the first step on the pathway to suicide. Despite the fact that suicidal ideation is surprisingly prevalent among preadolescent children in China and elsewhere, and despite its possible increase during the transition into adolescence, its developmental patterns and predictors during this period are unclear, thus precluding a meaningful understanding of its determinants and possible trajectories. Thus, this study aimed to identify suicidal ideation trajectories and multisystemic predictors covering the transition from middle childhood to early adolescence. A total of 715 Chinese elementary school students (M_age = 8.95, SD = 0.71; 54.5% was male) participated in assessments at six time points, using six-month assessment intervals. Growth mixture modeling analyses extracted three distinct trajectories of suicidal ideation: "low-stable" (86.4%), "moderate-increasing" (7.1%) and "high-start" (6.5%). Multivariate logistic regression analyses revealed that social anxiety and academic anxiety served as risk factors for the adverse developmental trajectories of suicidal ideation; whereas self-esteem, life satisfaction, and academic achievement served as protective factors for the positive developmental trajectory of suicidal ideation. The identification of three subgroups with unique predictors highlights the importance of individual difference considerations in understanding the progression of suicidal ideation in childhood and adolescence and the need for specific programs tailored to the unique characteristics of the relevant trajectories. Furthermore, given that suicidal ideation may start in a proportion of middle childhood youths and continue into adolescence, the middle childhood period should provide an important window of opportunity for large-scale screening and prevention of the escalation of suicidality in adolescence.

Heterogeneity in Short-Term Suicidal Ideation Trajectories: Predictors of and Projections to Suicidal Behavior

OBJECTIVE

Little is known about suicidal ideation stability, including whether stability is heterogeneous or homogeneous between individuals. Studies of this kind are necessary to understand the progression from suicidal ideation to action.

METHOD

This study examined suicidal ideation trajectories, using growth mixture modeling, in a sample of 359 past/current military service members (M age = 32.1 years, SD = 7.7; 88.3% male). Self-reported suicidal ideation information was collected at baseline and follow-up sessions at months 1, 3, 6, and 12. Following extraction of the best-fitting solution, predictors of trajectory status were examined and trajectory status was used to predict suicidal behavior between baseline and month 12 assessments.

RESULTS

Results revealed four trajectories, Low-Stable (n = 125), Moderate-Stable (n = 101), High-Stable (n = 76), and High-Rapidly Declining (n = 57). In general, the High-Stable trajectory had the highest levels of perceived burdensomeness, thwarted belongingness, PTSD symptoms, and drug use. The High- and Moderate-Stable trajectories had the highest rates of suicidal behavior between baseline and month 12.

CONCLUSIONS

Suicidal ideation, even in individuals with elevated ideation, is not a homogeneous construct over time. Stability of suicidal ideation might be an important risk factor, even if ideation is only moderately elevated.

Ethnic Variations of Trajectories in Suicide Ideation and Attempt: From Middle School to High School

The purpose of this study was to compare patterns of suicide ideation and suicide attempt in three ethnic groups. We analyzed data from 463 students with ethnic backgrounds of African American (AA), Asian American (ASA), and European American (EA) for 6 years. The best fit model was a three-trajectory class model for all groups. The majority of adolescents belonged in the nonideators trajectory. The high level of ideation was found in the high ideators (4%), high-fluctuating ideators (8%), and high-decreasing ideators (4%) trajectory in AA, ASA, and EA, respectively. In the AA group, being a member of ideators was not a significant predictor of suicide attempt. In the ASA group, being a member of high-fluctuating ideators was a significant predictor. In the EA group, being a member of both ideators predicted suicide attempt. The timing of onset, patterns of change, and peak time in the ideators trajectories in the three ethnic groups were markedly different. The high level of attempts found in the ASA-AA group was not explained by having suicide ideation. Findings suggest the need for in-depth examination of suicide behaviors across ethnic groups and culturally adapted preventive efforts with distinct developmental timing for adolescents from different ethnic backgrounds.

Associations of adverse childhood experiences and social support with self-injurious behaviour and suicidality in adolescents

BACKGROUND

There is little investigation on the interaction effects of adverse childhood experiences (ACEs) and social support on non-suicidal self-injury (NSSI), suicidal ideation and suicide attempt in community adolescent populations, or gender differences in these effects.AimsTo examine the individual and interaction effects of ACEs and social support on NSSI, suicidal ideation and suicide attempt in adolescents, and explore gender differences.

METHOD

A school-based health survey was conducted in three provinces in China between 2013-2014. A total of 14 820 students aged 10-20 years completed standard questionnaires, to record details of ACEs, social support, NSSI, suicidal ideation and suicide attempt.

RESULTS

Of included participants, 89.4% reported one or more category of ACEs. The 12-month prevalence of NSSI, suicidal ideation and suicide attempt was 26.1%, 17.5% and 4.4%, respectively; all were significantly associated with increased ACEs and lower social support. The multiple adjusted odds ratio of NSSI in low versus high social support was 2.27 (95% CI 1.85-2.67) for girls and 1.81 (95% CI 1.53-2.14) for boys, and their ratio (Ratio of two odds ratios, ROR) was 1.25 (P = 0.037). Girls with high ACEs scores (5-6) and moderate or low social support also had a higher risk of suicide attempt than boys (RORs: 2.34, 1.84 and 2.02, respectively; all P &lt; 0.05).

CONCLUSIONS

ACEs and low social support are associated with increased risk of NSSI and suicidality in Chinese adolescents. Strategies to improve social support, particularly among female adolescents with a high number of ACEs, should be an integral component of targeted mental health interventions.Declaration of interestNone.

Negative peer social interactions and oxytocin levels linked to suicidal ideation in anxious youth

BACKGROUND

Anxious youth are at risk for negative peer interactions including peer victimization, and for suicidal ideation. However, data about the pattern of association between these two factors are scarce. In this study we examined the association between negative peer interactions and suicidal ideation in a sample of children and adolescents with anxiety disorders, and whether oxytocin, which has been shown to enhance the impact of social events, moderates the impact of negative peer interactions on suicidal ideation.

METHOD

Participants were 168 youths with primary anxiety disorders. All participants were assessed with semi-structured diagnostic interviews, and with self-report measures of suicidal ideation, negative peer interactions, anxiety, and depression. The anxious youths' salivary oxytocin levels were measured with immunoassay.

RESULTS

Thirty percent of the anxious youths reported suicidal ideation, with suicidal ideation severity associated with negative peer social interactions and depressive symptoms. Consistent with past data indicating that oxytocin enhances the impact of social events, the association between peer negative social interactions and suicidal ideation was stronger in youths with high oxytocin levels than in youths with low levels (i.e., moderation).

LIMITATIONS

Assessment focused on suicidal ideation and data on suicidal behavior were not available. Limitations inherent to immunoassay measurement of peripheral oxytocin levels are noted.

CONCLUSION

Negative peer interactions are associated with suicidal ideation in youth with anxiety disorders, and the association is stronger in youth with high oxytocin levels.

Exposure to maternal depressive symptoms in childhood and adolescent suicide-related thoughts and attempts: mediation by child psychiatric symptoms

AIMS

The nature of the association between child psychiatric symptoms and adolescent suicide-related thoughts (SRT) and attempts (SA) remains unclear. Our objective was to assess whether child psychiatric symptoms from 6 to 10 years of age mediate the association between exposure to maternal depressive symptoms in childhood and offspring SRT and SA in adolescence.

METHODS

A population-based cohort study was constructed by linking all eight cycles from the National Longitudinal Survey of Children and Youth (NLSCY), a nationally representative Canadian panel survey conducted from 1994 to 2009. Self-reported maternal depressive symptoms were measured when offspring were between 0 and 5 years. Maternal-reported child psychiatric symptoms and psychiatric comorbid symptoms were measured from 6 to 10 years, and offspring self-reported SRT and SA were measured between 11 and 19 years. Indirect effects, the effect proportion mediated and their corresponding bootstrapped 95% confidence intervals (CI) were estimated.

RESULTS

Hyperactivity and inattention significantly mediated the association between maternal depressive symptoms in childhood and risk of both SRT and SA from 11 to 19 years, where approximately 60% (SRT 95% CI 23-94%; SA 95% CI 27-95%) of this association was explained by hyperactivity and inattention. Psychiatric comorbid symptoms also significantly mediated this relationship and accounted for 50% (95% CI 18-81%) of this association with SA.

CONCLUSIONS

Targeting hyperactivity and inattention, and co-occurring psychiatric symptoms in offspring of depressed mothers could reduce risk of SRT, eventual SA and halt progression towards suicide. However, further understanding of comorbid psychiatric symptoms in childhood that most strongly predict adolescent SA is needed.

The impact of psychological problems and adverse life events on suicidal ideation among adolescents using nationwide data of a school-based mental health screening test in Korea

The aim of this study was to investigate the risk factors for suicidal ideation in adolescents by gender and age. This study used 2013 nationwide school-based mental health screening test data from 591,303 seventh grade students and 618,271 tenth grade students in Korea. Suicidal ideation, four psychological problems, and three adverse life events were evaluated using the Adolescents Mental Health and Problem Behavior Screening Questionnaire-II. Of all students, 12.9-14.7% of the boys and 17.1-23.2% of the girls had suicidal ideation. Mood had the greatest impact on the risk for suicidal ideation and other factors also significantly increased the risk of suicidal ideation. Distractibility was positively related to suicidal ideation only in seventh grade students and behavioral problems increased suicidal ideation more in girls than in boys. Violence constituted the most powerful factor for suicidal ideation among the events; however, bullying constituted the most important event that increased suicidal ideation in seventh grade girls. All factors except 'Distractibility' increased the risk of severe suicidal ideation. The risk factors for suicidal ideation in adolescents differed by gender and age. Interventions should be made according to these characteristics to reduce suicidal ideation in adolescents.

Family Patterns and Suicidal and Violent Behavior among Adolescent Girls-Genogram Analysis

An increase in extreme self-destructive and aggressive behaviors in adolescents has been observed in recent years. Therapeutic effectiveness seems to depend on an adequate recognition of factors that might increase the risk of extreme destructive behaviors. The aim of this study was to identify the family patterns that should draw therapeutic attention due to their importance for suicidal or violent behaviors in adolescent girls. The study involved 140 participants, aged 13⁻17, including 40 girls after suicide attempts, 40 girls using violence, and 60 girls without destructive behavior at all. The Genograms were used to assess the family structure, relationships between family members, and family projections. The data was analyzed by polynomial logistic regression, analysis of variance, and discriminant analysis. Emotional distance and hidden projections (related to diseases) were the most significant predictors of suicidal behaviors in the studied adolescent girls. Alcohol abuse by significant family members, especially by male family members, and a lesser role of hidden projections, were the most significant predictors of violent behaviors. Interventions designed to reduce risk of destructive behaviors among adolescents need to take account of the specific family patterns.

The influence of family factors on time to suicidal ideation onsets during the adolescent developmental period

Family factors are associated with suicidal behavior in youth, but little is known about how the joint influence of multiple family factors prospectively predicts onsets of suicidal ideation (SI) in adolescence, a developmental period characterized by increases in SI and risk for suicide. This study investigated whether parent history of SI interacted with either positive or negative parent-child relationship quality to longitudinally predict time to SI onsets during the transition into and across adolescence. Specifically, we used a longitudinal, multi-wave design and survival analyses to examine whether the interaction between these family factors prospectively predicted time to emergence of SI onsets (assessed at 6 month intervals over 3 years) in a community sample of youth ages 8 to 15 (N = 238; 57% girls). Results supported an interaction effect, such that more negative relationship quality with parents predicted earlier emergence of SI among those youth whose parents had no history of SI. However, negative parent relationship quality did not amplify risk among youth with parent history of SI; all youth with a parent history of SI were more likely to experience earlier emergence of SI regardless of level of negative relationship quality. Findings did not support an interaction between low levels of parent-child positive relationship quality and parent history of ideation. Implications for the role of family factors in the etiology and prevention of SI are discussed.

A Review of the Academic and Psychological Impact of the Transition to Secondary Education

The transition from primary to secondary education is one of the most stressful events in a young person's life (Zeedyk et al., 2003) and can have a negative impact on psychological well-being and academic achievement. One explanation for these negative impacts is that the transition coincides with early adolescence, a period during which certain psychological disorders (i.e., anxiety disorders) become more salient (Kessler et al., 2005) and marked social, biological, and psychological development occurs (Anderson et al., 2000). This review evaluates the existing literature on the psychological and academic impacts of the transition to secondary education on young adolescents. We examine the factors that plausibly increase or mitigate the risk of developing mental health issues and/or a decline in academic performance during the transition to secondary education. We also review the interplay between psychological health and academic achievement across and beyond the transition. We conclude with a summary of what schools and parents can learn from these findings to support children in a successful transition into secondary education.

The psychic readiness for destruction among contemporary adolescents

AIMS AND OBJECTIVES

To verify the existence of psychic readiness for destruction among adolescent girls and to determine how psychic readiness for destruction is related to suicidal or violent behaviour in adolescence.

BACKGROUND

The psychic readiness for destruction can be treated as a generalised tendency (personality disposition) to behave in a way that increases the probability of negative consequences which directly and indirectly threaten one's life, health and its quality.

DESIGN

A retrospective cross-sectional study.

METHODS

The study involved 140 participants, aged 13-17, including 40 girls after suicide attempts (GS group), 40 girls using violence against others (GA group) and 60 girls without destructive behaviour at all (CG group). To measure psychic readiness for destruction, the polish adaptation of the Chronic Self-Destructiveness Scale (CS-DS) by Kelly was used.

RESULTS

No significant differences were found between the GS group and GA group. A significant difference was found between the girls who engage in interpersonal violence (GA) and the control group (CG). In this case, the results showed a significantly higher score among those participants who were involved in extremely aggressive behaviours. A similar trend was also observed when comparing the group of girls who attempted suicide (GS) with the CG.

CONCLUSIONS

Based on the conducted analyses, a clear trend was observed in consistency of destructive behaviours (tendency for destruction)-both active (seeking to violate norms, risky behaviours) and passive (omission, neglect) among the girls from both groups indicating even a single act of this kind (no significant differences between the groups).

RELEVANCE TO CLINICAL PRACTICE

Due to the complex nature of readiness for destruction and its negative consequences on health, it is imperative to investigate the risk factors for the tendency for destruction and to conduct health education among adolescents.

Does cyberbullying impact youth suicidal behaviors?

Even though several youth fatal suicides have been linked with school victimization, there is lack of evidence on whether cyberbullying victimization causes students to adopt suicidal behaviors. To investigate this issue, I use exogenous state-year variation in cyberbullying laws and information on high school students from the Youth Risk Behavioral Survey within a bivariate probit framework, and complement these estimates with matching techniques. I find that cyberbullying has a strong impact on all suicidal behaviors: it increases suicidal thoughts by 14.5 percentage points and suicide attempts by 8.7 percentage points. Even if the focus is on statewide fatal suicide rates, cyberbullying still leads to significant increases in suicide mortality, with these effects being stronger for men than for women. Since cyberbullying laws have an effect on limiting cyberbullying, investing in cyberbullying-preventing strategies can improve individual health by decreasing suicide attempts, and increase the aggregate health stock by decreasing suicide rates.

Longitudinal risk factors for suicidal thoughts in depressed and non-depressed young adolescents

OBJECTIVE

Evidence regarding the role of risk factors in the longitudinal course of suicidal ideation among young adolescents is lacking. We aimed to assess the effects of a range of risk factors, including obesity, academic performance, child-parent relationship, physical maltreatment, and depressive symptoms, on the development of suicidal ideation in young adolescents.

METHODS

A school cohort of seventh and eighth graders was followed for 1 year and differences in the risk factors distributions were examined between depressed and non-depressed adolescents. We further examined risk factors for newly developed suicidal ideation and persistent suicidal ideation in the groups of adolescents based on the presence of suicidal ideation at baseline.

RESULTS

A total of 1710 young adolescents were recruited, among whom 8.2% were categorised as having clinically significant depression. For depressed adolescents, being obese was associated with a three-fold increased risk of having suicidal ideation. For non-depressed adolescents, physical maltreatment, a feeling of not being cared about and sub-threshold depressive symptoms were the risk factors. The latter two remained robust in predicting newly developed suicidal ideation.

CONCLUSION

The current study may shed light on the differential strategies to address suicidal thoughts in depressed and non-depressed adolescents. We emphasise the importance of recognition and management of sub-threshold depressive symptoms and the relevance of obesity, physical maltreatment and a feeling of not being cared about to suicide prevention programmes in early adolescence.

Risk Factors for Suicide Ideation Among Adolescents: Five-Year National Data Analysis

This study identified risk factors for suicide ideation among adolescents through a secondary analysis using data collected over five years from the 5th-9th Korea Youth Risk Behavior Survey. We analyzed 370,568 students' responses to questions about suicidality. The risk factors for suicide ideation included demographic characteristics, such as gender (girls), low grades, low economic status, and not living with one or both parents. Behavioral and mental health risk factors affecting suicide ideation were depression, low sleep satisfaction, high stress, alcohol consumption, smoking, and sexual activity. Health care providers should particularly target adolescents manifesting the above risk factors when developing suicide prevention programs for them.

Association between Suicide Ideation and Attempts and Being an Immigrant among Adolescents, and the Role of Socioeconomic Factors and School, Behavior, and Health-Related Difficulties

The risk of suicide behaviors in immigrant adolescents varies across countries and remains partly understood. We conducted a study in France to examine immigrant adolescents' likelihood of experiencing suicide ideation in the last 12 months (SI) and lifetime suicide attempts (SA) compared with their native counterparts, and the contribution of socioeconomic factors and school, behavior, and health-related difficulties. Questionnaires were completed by 1559 middle-school adolescents from north-eastern France including various risk factors, SI, SA, and their first occurrence over adolescent's life course (except SI). Data were analyzed using logistic regression models for SI and Cox regression models for SA (retaining only school, behavior, and health-related difficulties that started before SA). Immigrant adolescents had a two-time higher risk of SI and SA than their native counterparts. Using nested models, the excess SI risk was highly explained by socioeconomic factors (27%) and additional school, behavior, and health-related difficulties (24%) but remained significant. The excess SA risk was more highly explained by these issues (40% and 85%, respectively) and became non-significant. These findings demonstrate the risk patterns of SI and SA and the prominent confounding roles of socioeconomic factors and school, behavior, and health-related difficulties. They may be provided to policy makers, schools, carers, and various organizations interested in immigrant, adolescent, and suicide-behavior problems.
